I do not think (not sure) I have done that, but I have poured coolant in radiator without drain plug, oil in engine with no drain plug, tried to split without removing flywheel inspection cover, started one without oil in touch control, and also without the pin in governor to throttle linkage. Had to rebuild TC pump after that one. There are probably more I have done, but my memory is bad. Also, my memory is bad.
